Patent EP-0466238-A2 (EP)
Inventor: FLETCHER THOMAS DALE
IPC: H03K19/003
Filed: 1991-06-27
Abstract: In a driver circuit, high- and low-impedance drive means (26 and 28 respectively) operate in parallel to effect a desired output transition. Adaptive control means 32 respond to a threshold value of the output signal (VO) and turn off the low-impedance drive means in the course of the output transition. The low initial output impedance of the driver circuit effects rapid charging of a line capacitance CL, while toward the end of the output transition the higher output impedance of the driver circuit more closely matches the input impedance ZL of a load circuit. This higher impedance dampens ringing and thereby reduces induced suppy line noise which is conventionally associated with high-speed driver circuits.

Abstract: A memory fault mapping apparatus detects faults generated in a memory array during on-line operation. As the memory array 1, 2 is randomly accessed, single bit errors are detected, corrected, and mapped into an error memory 13. The error memory may have a memory location for each memory of the memory array or alternatively, by grouping memories together and when the errors generated by any one group exceeds a predetermined threshold of errors, testing only the memories in that group off-line. By grouping the memories a substantial reduction in the amount of error memory required can be achieved. A SEC/DED syndrome generator 8 detects single and double bit errors, correcting the single bit errors while providing an indication of which memory generated the error. The error memory stores error counts for the memory array, each error count indicating the number of errors for a specific memory or a group of memories. The error counts are incremented by loading the error count into a counter 15 for incrementing then writing the incremented error count back to the error memory location from which it was read.

Abstract: A method and apparatus for the management of the data associated with multiple graphics contexts in a computer graphics rendering system. Graphics contexts are built by graphics engines and selectively saved into a context save RAM. Context switches are managed either by modifying a context base pointer to address a new section of the context save RAM, or by writing out a portion of the context save RAM to external storage and reading in a replacement context from external storage. The writing and reading process are managed by a control processor allowing the graphics engines to switch context at the same time. New contexts read from external storage automatically cause regeneration of downstream rasterization parameters.

Abstract: A compact ink jet print head has cross-sectionally tapered ink manifolds (16) for supplying ink to ink supply channels (18) leading to the acoustically driven ink pressure chambers (22). An array of closely spaced nozzles (14) which are supplied with ink from the densely packed ink pressure chambers by way of offset channels (71). The tapered manifolds, ink supply channels, pressure chambers, and offset channels are designed to provide uniform operating characteristics among the ink jet nozzles of the array. To enhance the packing density of the pressure chambers, the ink supply channels leading to the pressure chambers and offset channels are positioned in planes between the pressure chambers and nozzles. The tapered ink supply manifolds enhance purging of contaminants or bubbles from the print head by providing uniform ink flow rates (97, 97') along the entire length of the manifolds. Optional ink purging channels (42) are provided for purging bubbles and other contaminants from the print head without requiring ink flow through the nozzles. The ink jet print head may be assembled from multiple plates with features in all but the nozzle-defining plate being formed by photo-patterning and etching processes without machining or other metal working.

Abstract: Apparatus and a method are disclosed for detecting and evaluating optical subcircuits created by optical splitters (203) in an optical circuit. One or more optical wavelengths are utilized for the transmission of data, whereas other optical wavelengths are utilized to perform optical time domain reflectometry measurements on each optical subcircuit. Following an optical splitter, each optical path from the optical splitter has inserted into it an optical filter (204, 209) which allows the transmission of the optical wavelengths utilized for data transmission and one of the optical wavelengths utilized to perform the optical time domain reflectometry measurements. An optical time domain reflectometry instrument (201) transmits each of the optical wavelengths, utilized for testing, individually into the optical circuit and analyses the returned optical pulse. Since only one optical subcircuit allows the passage of any given optical wavelength for testing, each optical subcircuit can be fully analysed.

Abstract: The invention relates to a system for transmitting stored programs, such as movies and musical works, to customers via a distribution network (112, 115, 114, 116), such as a cable television system. The programs are stored in compressed form in a program library (102), such as a tape cartridge library. On receipt of a request (on 103) for a program, a request processor (101) sends control messages causing a data block comprising the requested program to be read from the program library (102) at high speed and stored in a large dynamic random access memory (DRAM) (111) in a server (100). The server then sends the program from DRAM over the distribution system (112, 115, 114, 116) to a customer as a series of digital packets. Each instance of sending a program is managed by a separate command word. The customer can request such operations as "fast forward" by sending control messages that change pointers in the command word. Command words can be grouped to send multiple audio and/or video overlays simultaneously and linked to send program sequences. The request processor (101), server (100), program library (102) and interfaces to distribution networks can be at different locations.

Abstract: An apparatus and method have been conceived for using a digital audio tape (DAT) in an audio logger for the purposes of storing and retrieving audio data. This is accomplished in a manner such that the data is received and recorded in a time related manner. Provision is made for accommodating the transfer drive rate of the DAT through use of a buffer between the signal processor of the logger and the DAT. In addition, the method of storing the data results in greater use of the available space on the DAT as the DAT tape only writes for those periods when audio is present on a channel.

Abstract: A computer-controlled injector (40) of the type having a motor which advances and retracts a plunger (12) located within a syringe housing (10) toward and away from a nozzle located in the front of the syringe to inject fluid into or out of an animal subject. Manual motion is induced by operating a manual motion control (44-48); the operator can manipulate the control to indicate the desired direction and velocity of motion. The manual motion control also has a locking mode in which manual motion of the plunger will continue once initiated without requiring the operator to continue manipulating the manual motion control. The injector performs injections in accordance with one of several pre-programmed protocols, and automatically tracks the fluid volume remaining. The injector compensates for plunger extenders found in some partially pre-filled syringes by applying a stored offset value to the computed plunger position.
